To all whom it may concern:

Be it known that I, JAMES THORNTON, of Wellsville, in the county ofAllegany and State of New York, have invented a certain Improvement inHaine-Staples, of which the following is av specification My inventionconsists of a new and improved haine-staple as an article ofmanufacture, as will be hereinafter more fully set forth.

In the accompanying drawings, Figure l is an elevation of a portion of ahaine provided with my improved. staple. spective view of the stapledetached.

Like letters of reference designate like parts in each of the figures.

A is the llame, B the llame-staple proper, and b a cross-bar, connectingthe two legs of the staple in front, and bent outward so as to form aloop, with which a snap-hook of a holdback-strap may directly engage. Cis a loop-hook, connected with the loop b so as to form suitable meansfor engaging a leathern Fig. 2 is a perholdback strap therewith, whenthe latter are not providce"` with snap-hooks.

My improved staple can be :readily cast of malleable iron at but atriliing cost above that of an ordinary staple, whereby the expense andlabor of applying a separate attachment for the holdback-strap areavoided, as well as the weakening of the hamc, which results fromforming a hole for the eyebolt of the ham e-strap ring through it atright angles to the holes for the staple, and in near proximity thereto,as is ordinarily done where a separate attachment is used for theholdback strap.

What I claim as my invention is As a new article of manufacture, thellamestaple B provided with two penetrating prongs and a curved bridge,b, substantially as shown.
